Siegfried Sassoon is the greatest and most famous of all British war poets. In this complete biography of his life, John Stuart Roberts reveals the truth behind a very private persona. Established as a poet before the Great War broke out, his near-suicidal courage in the face of enemy fire won him a Military Cross - and the nickname Mad Jack. War hero, pacifist, towering literary figure; this is a gripping account of a deeply complex and enigmatic man.
